Casio Oceanus Manta OCW-S7000-1A
The Oceanus is Casio's analog line in titanium, and the S7000 series arrived as three regular models alongside a limited S6000 with a spiral-cut sapphire bezel. The OCW-S7000-1A is the plainest of them, a uniform black dial under a smooth dark blue bezel ring made of sapphire, which lets light through to the solar cell beneath it. The titanium case and bracelet are hardened with a carbide treatment and finished with a silver coating. The watch is 42.8 mm across and only 9.5 mm thick, weighs 83 g, and is rated to 100 m. Inside is Tough Solar with Multi-Band 6 radio time-setting and Bluetooth, so the world time and other settings can be run from the Casio Watches app. Worn & Wound reported it at $1,300, the least expensive of the three.
